Abstract (en)
[origin: WO9509338A1] A heat exchanger (1) for two flowing fluids (A, B) has parallel flow channels (4) whose cross-section is formed by layered and superimposed boards with a sinuous profile. Each board covers the flow channels (4) of the underlying board. Different fluids can flow through flow channels (4) located side by side. The inner angle theta of the open trapeziums formed by the sinuous profile has less than 90 DEG . Thanks to this small inner angle, each board lies on the underlying board and is prevented from intermeshing with it. This helps to increase stability at higher differential pressures and allows the weight of the heat exchanger to be reduced.
